I want a program that will listen UDP on port 7777 and give some answer. Why do I want that? I have a game server running on port 7777 and I want to give a fake query response for players (only change the number of players online) So, I see 2 options: 1) If you can, the best would be make the aplication read the packet, check if it is query and answer before game server (if you can do that I can pay an extra gig) or 2) If you can't, the other way is also ok, I'll get an other server only to run this aplication and I'll redirect query packets using iptables -t NAT option 2 is easier for you, but if you can make option 1 that would be very good, we can negociate price if you want. and the last question: What is the information to send and to receive?

I am very proficient in c, c++. I have 15 years c++ developing experience now, and I have worked for 5 years. My work is online game developing, and mainly focus on server side, the language is c++ under linux. I used c++ to make many great projects, for example, I made the tools which can convert java files to c++ scripts which has the same effect, of course garbage collection included. I also made our own mobile game using c++, I even can show you the demo of client. Trust me, please let expert help you.

Hi I understand the requirement. I think we can do the first way itself if you can supply the message format.

hello, you can't have two applications running on the same port of the same machine. place your confidence in my C and networks knowledge and experience to successfully derive a specification that'll work for you, and then implement it. greets, srdjan

Sir, Listening on udp port & replying is fine. But the message format is more important. If the message format is clear, we might also be able to achieve the first option. Thanks.

This is the first time am bidding for any project. I have spent almost 11 years in software industry working mostly on C / C++ code. As of now i can commit 10 hours per week. Am doing freelancing in my free time to generate some money. So if you under some time constraint or urgent need then i may not be that use-full. I have worked on protocol severs( like UDP / HTTP ) before. My understanding is you need a handler code which will be invoked for "specific message" sent by gaming client. This specific handler code will be part of game server running on port 7777. So as you understand am preferring solution to go with option 1 ( that you have suggested ). This also means you may need to share the source code of gaming server or may be some secure system with VPN access. My understanding is that if am selected to work on this, I shall do following 1. Understand your existing code so that i can add new code. 2. Do the code changes following your coding style/pattern. 3. test with the test-plan discussed with you. 4. You must have static/dynamic analysis tool like valgrind to check memory leaks/corruption. Above points are minimal but just to give an idea. I think all this should not take more than 20 hours, but your server code may be complex. Also i don't know if i understand your requirement fully. So if you decide to give this project to me then we need to discuss and decide about milestones. Let me know if you need more information. regards Deepak

We will develop option 1 for you. Can you provide the details of how the query will look like and what will be the response which the application should send.
